  "description": "Compares the total cost and risk-adjusted exposure of Documentary Collections (D/P, D/A) against Letters of Credit (Sight, Usance, Confirmed, SBLC) for a trade transaction. Returns a fee breakdown, break-even non-payment probability, and a recommendation, plus a disclosed heuristic LC protection score. Provable node counterpart to tools/423-dc-vs-lc-analyzer.html; that tool page's URC 522 checklist and jurisdiction D/A enforceability reference panels stay browser-only reference material, not computed outputs.",
